Conrad Playground Supply underwent a restructuring in 2021. The company conducted a thorough internal audit, during which the following facts were discovered. The audit occurred during 2021 before any adjusting entries or closing entries are prepared.

1. Additional computers were acquired at the beginning of 2019 and added to the companys office network. The $47,500 cost of the computers was inadvertently recorded as maintenance expense. Computers have five-year useful lives and no material salvage value. This class of equipment is depreciated by the straight-line method.

3. On December 31, 2020, merchandise inventory was understated by $83,000 due to a mistake in the physical inventory count. The company uses the periodic inventory system.
